Watch your computer connect across the internet in real time. Discover the world behind your apps.
Open source • Runs locally • No telemetry
Most users are unaware of how much network activity takes place in the background. Some connections are expected. Others may come as a surprise.
The map makes this activity visible by showing what is connecting and where. The last 30 days of activity help you understand what you see regularly and what appears only briefly.
TapMap is an awareness tool, not a firewall or a security suite. Its purpose is to make network activity visible and easy to explore.
TapMap processes network connection data locally on your computer.
Install TapMap using a Windows installer, macOS disk image, or Debian package. No Python setup is required. The macOS app is signed and notarized.
See which app is connecting, who created the app, and whether it is verified by your operating system. Technical details remain available when you want them.
TapMap continues running after you close the browser. Open or quit it from the system tray on Windows and Linux or the menu bar on macOS. TapMap can also start automatically when you log in to your computer.
See when TapMap notices a new app, country, network provider, or remote port, or when an app fails verification. Review the latest 500 events in a separate history.
Publish new Significant Connections to an MQTT broker you configure. This is especially useful when TapMap runs in Docker, where desktop notifications are not available. MQTT also works on Windows, Linux, and macOS.
While TapMap runs in the background to build its activity history, native desktop notifications alert you when it notices a Significant Connection. Notifications can be turned on or off in TapMap.
"It makes the invisible visible."
"The insights panel made me keep the tool running long after the novelty of the map wore off."
